$B_c$ meson decays into $S$-wave charmonium plus light meson pairs in the perturbative QCD approach

Jia-Ying Wang, Jing Jiang, Yu-Jie Liu +4

In this work, we explore the $P$-wave resonance contributions to the three-body charmonium decays of $B_c\to \hat{I}¨(V\to )P_1{P}_2$ using the perturbative QCD formalism at leading order,…
